Awukho umehluko phakathi kwe-carbon brush DC motor kanye ne-brush DC motor empeleni, njengamabhulashi asetshenziswa kuyoDC motorsngokuvamile amabhulashi ekhabhoni. Nokho, ukuze kucace kwezinye izimo, lezi ezimbili zingase zishiwo futhi ziqhathaniswe nezinye izinhlobo zamamotho. Okulandelayo yincazelo enemininingwane:

Ibhulashi DC Motor

• Isimiso Sokusebenza: Imoto ye-DC ebhulashiwe isebenza ngezimiso zokungeniswa kuka-electromagnetic kanye nomthetho we-Ampere6. Iqukethe izingxenye ezifana ne-stator, rotor, amabhulashi, kanye ne-commutator. Lapho umthombo wamandla we-DC unikeza amandla enjini ngamabhulashi, i-stator ikhiqiza inkambu kazibuthe emile, futhi i-rotor, exhunywe kumthombo wamandla ngamabhulashi kanye ne-commutator, yakha inkambu kazibuthe ezungezayo. Ukusebenzisana phakathi kwenkundla kazibuthe ezungezayo kanye nenkundla ye-stator kukhiqiza i-torque kagesi, eshayela injini ukuthi ijikeleze. Ngesikhathi sokusebenza, amabhulashi ayashelela ku-commutator ukuze ahlehlise amandla amanje futhi agcine ukuzungezisa okuqhubekayo kwenjini6.
• Izimpawu Zesakhiwo: Inesakhiwo esilula, ikakhulukazi esihlanganisa i-stator, i-rotor, amabhulashi, kanye ne-commutator. I-stator imvamisa yenziwe ngamashidi ensimbi e-silicone aminated anezilonda ezizungezile. I-rotor iqukethe i-iron core nama-windings, futhi ama-windings axhunywe kugesi ngokusebenzisa amabhulashi6.
• Izinzuzo: Inokufaneleka kwesakhiwo esilula nezindleko eziphansi, okwenza kube lula ukuyikhiqiza nokuyinakekela. Iphinde ibe nokusebenza okuhle kokuqala futhi inganikeza i-torque enkulu yokuqala6.
• Ukungalungi: Ukungqubuzana nenhlansi phakathi kwamabhulashi nesihambisi ngesikhathi sokusebenza kuholela ekugugeni, kunciphisa ukusebenza kahle kwenjini neminyaka yokuphila. Ngaphezu kwalokho, ukusebenza kwayo kokulawula isivinini kubi kakhulu, okwenza kube nzima ukuzuza ukulawulwa kwesivinini okunembile6.

I-Carbon Brush DC Motor

• Isimiso Sokusebenza: I-carbon brush DC motor empeleni iyinjini ye-DC exutshwe, futhi isimiso sayo sokusebenza siyefana naleso se-DC motor exutshwe echazwe ngenhla. Ibhulashi lekhabhoni lixhumene nomhambisi, futhi njengoba umshayeli ejikeleza, ibhulashi lekhabhoni lishintsha ngokuqhubekayo indlela yamanje ku-coil ye-rotor ukuze kuqinisekiswe ukujikeleza okuqhubekayo kwe-rotor.
• Izimpawu Zesakhiwo: Isakhiwo ngokuyisisekelo sifana naleso senjini ye-DC exutshwe jikelele, okuhlanganisa i-stator, rotor, carbon brush, kanye ne-commutator. I-carbon brush ngokuvamile yenziwe nge-graphite noma ingxube ye-graphite ne-metal powder, ene-conductivity kagesi enhle kanye nezakhiwo zokuzigcoba, ukunciphisa ukuguga phakathi kwebhulashi kanye ne-commutator ngezinga elithile.
• Izinzuzo: Ibhulashi lekhabhoni linezinto ezinhle zokuzithambisa futhi ezingagugi, ezinganciphisa imvamisa yokushintshwa kwebhulashi kanye nezindleko zokulilungisa. Ibuye ibe nokuhamba kahle kagesi futhi ingaqinisekisa ukusebenza kahle kwemoto.
• Ukubi: Nakuba ibhulashi lekhabhoni linokumelana kangcono nokugqokwa kunamanye amabhulashi ajwayelekile, lisadinga ukushintshwa njalo. Ngaphezu kwalokho, ukusetshenziswa kwamabhulashi e-carbon kungase futhi kukhiqize enye i-carbon powder, okudingeka ihlanzwe njalo ukuze ivimbele ukuthi ingaphazamisi ukusebenza kwemoto.
